Dextrose is the name of a simple sugar that is made from corn and is chemically identical to glucose, or blood sugar. Dextrose is often used in baking products as a sweetener, and can be commonly found in items such as processed foods and corn syrup.
Dextrose also has medical purposes. It is dissolved in solutions that are given intravenously, which can be combined with other drugs, or used to increase a person’s blood sugar.
Because dextrose is a “simple” sugar, the body can quickly use it for energy.
